Can someone please help a total noob (first post too). I have a nuvi 1250. I downloaded the file listing in the 1st post, unrared and got a 19.856 meg file called gmapsupp.img.

I then:
1. Downloaded the GarminUnlockerAlternative_v2.4 file
2. I unrared and and read the readme file and followed the directions to place the img file in the "locked" folder.
3. I ran the Unlock Map Directory.exe file
4. I got an error saying:

"something is wrong Unlocked MAP not created
Source IMG file must be in directory named: MAP Locked
Only one source IMG file same time in directory named: Map Locked"

Not sure why since I only have the one img source in that folder.

Can anyone help? I'm stuck and can't use it like this. Maybe I missed a step? The maps on my old GPS are now so out of date they are worthless. I specifically bought the Nuvi to work with this (though am tempted to upgrade to the 1260 to get the bluetooth feature). But the nuvi is worthless to me if i can't get these maps to work. Thank you!

Thanks. So what else am I doing wrong because when I drop this file into my Garmin system folder and then try to use the Garmin, I see no change whatsoever. When I click "go to map" I only see US map. I don't see any option to get an Israel map.

From other google searches I found references to using a special app to install maps and something called a webupdater to change the firmware but they did not go into any details at all - as if I should already know where to find this app and what to do with it. Any step by step instructions for noobs? Thanks so much, if I can't get this to work, I'll have to return the gps while I still can.

I tried copying and pasting the gmapsupp.img file to be with these other files but when I disconnected the garmin and turned it on, it seemed no different than before. Do I need to do something special to transfer the file over? Do I need a SUM file (whatever that is) to go along with the .img file?

I'm not so sure that gmapprom2.img would be acceptable for a nüvi as mentioned in the previous post. Try gmapprom1.img or gmapsupp.img instead.
SUM files are just check-sum data calculated when the unit uses the diagnostics mode.

The normal map IMG files to use:

gmapoem.img - Mostly for OEM data with customized POIs for the OEM reseller
